OK about 70 flashes in the last 2 minutes (9:30pm)( 41.44° N, 91.46° W) and based on the spacing of the flashes, I would guess ; more than 50 fireflies nice to see them again
OK, so we can assume the temp has briefly risen to 57C. Please Register or Log in to view the hidden image! Maybe its time to observe from indoors?
If 25C then per DaveC426913's info: 12/min/firefly. 70 flashes in 2 minutes would suggest 3 fireflies, not 50. Well, technically I guess 3 fireflies with one of them missing a leg, or other small bodily part. And 47 flashes would correspond with 2 fireflies originally. Corresponds fairly accurately to that table. Please Register or Log in to view the hidden image! Ah, the reverse Occam's Razor! Please Register or Log in to view the hidden image!

OK entertaining as the chart was it had zero relevance to the number of fireflies in the yard based on observation 50 seems more likely===maybe more pesticides, light pollution, loss of habitat, fireflies are under attack so my joy at seeing them is well ...............................
My bad. I presumed more precision than is warranted by those 2 decimal coords. They could round down or round up. So the precision is only to within this ~ 800m x 1200m rectangle: Please Register or Log in to view the hidden image! Which includes one house. Two, if we're being really generous. P.S. Wow.

ok Firefly season is nearing completion one or five females still blinking and maybe 10 males still flashing but almost over female bling in the grass-shrubs-etc males flash for a longer time and fly above the females looking for a hookup mostly they live underground and only come out for our enjoyment when they want to mate better than fireworks or the drivel on tv and then we get to see the bats patrolling the yard feasting on other flying insects all the entertainment needed right here in the back yard
